Recently, For one of my research paper, I need to know pseudocode or algorithm inside solvePnP's SOLVEPNP_ITERATIVE flag which is based on the Levenberg-Marquardt optimization.

Is there any way to find it? Please help.

Thanks in advance.

It is LM non-linear optimization method with the analytical form of the derivatives of the rotation matrix wrt. exponential coordinates. There are some references in the Rodrigues documentation.

Have a look at the documentation page: https://docs.opencv.org/

And search for Rodrigues documentation in the calib3d module.
